CONVERTIBLE PUNCHING BAG MOUNT Filed March 1, 1950 2 Sheets-Sheet 2INVENTOR HERBERT Rus'm ATTORNEY Patented June 16, 1953 UNITED STATESPATENT CONVERTIBLE PUNCHING BAG MOUNT Herbert Rubin, New York, N. Y. 7Application March 1, 1950, SerialNo. 146,945 I l V This inventionrelates to a device which may be employed to maintain a punching bagsupported by a resilient rod in a position upright from the floor sothat a user may stand upon 'a portion thereof and strike the bag andwhich device is convertible so that the same may be mounted upon avertical surface and support a dependent punching bag so that a user maystrike the bag so as to cause it to hit the platform portion of thedevice.

An object of my invention is to provide means 4 Claims. (01. 272-48) tosupport a punching bag upright from the floor and which same means isconvertible to means which are adapted to support a'punching bag whensecured to a vertical surface such as a wall.

Another object'of my invention is to provide sturdy means adapted tovertically support a punching bag upon a resilient rod upward from thefioorin a position for striking and which is nevertheless convertible towall 'mounting means for supporting a dependent punching bag which whenstruck, .will hit against a portion thereof in the form of a platform. s

7 Still another object of my invention is the provision of an articulatemount which may be rigidly connected to support upward from the floor apunching bag mounted on a resilient rod and portions of which may besopivotd as to convert the same into a mount which when secured to awall, will provide means for mainta'in' ing a dependent punching bag insuch a position that when struck, it willjbounce against a portionthereof in the forin of a platform.

These and other objects are accomplished by a mount which includes apreferably circular platform to which is pivotably connected a baseplate by means of longitudinally extending supporting bars oncorresponding sides of'said platform and base plate. Means are furnishedto-fix the base'plate in one position relative to the plat-' form. Saidmeans are disengageable'to permit the base plate to be pivotedlongitudinally rela' tive to said platform. A punching bag mounted on aresilient rod may be secured to means on the base plate so that when theplatform and base plate are rigidly connected a user'may stand upon theplatform and strike the punching bag. When the means to detachablysecure the base plate to the platform are disengaged, the elements ofthe mount may be swung so that sup-i port means associated with the baseplate and similar means on the platform may be brought against averticalsurface and secured thereto in such fashion that the platform extendslongitu- 2 dinallyin'a horizontal may be suspended therefrom.

Other objects anda fuller understanding of my invention may be had byreferrring to the following expanded description and claims, taken inconjunction with the accompanying drawings which illustrate .a'preferredembodiment thereof, it being. understood that the foregoing statementof-the objects. of my invention E and the'brief, summary thereof areintended, to

generally explain the same without limiting it in any manner.

Fig. 1 is a top plan view'of a-punchingbag mount constructed inaccordance with and em- I bodying my invention. r

Fig. 2 is an elevation view thereof showing a punching bag mountedvertically thereon.

Fig. 3 is a bottom plan view of the mount. Fig. 4-is an elevationviewthereof showing the mount secured to a wall andsupporting adependent punching bag.

Fig. 5 is a view in perspective thereof.

Fig. 6 is an enlarged fragmentary view in elevationof the platform ofthe mount broken away to show the means of affixation of the mountingchain.

Referring tothe drawings, the embodiment of my invention there shownincludes a preferably platform H1 and walls M of base plate l3, by

loosely engaging rivets and by machine screws which extend throughmatching apertures in the bars, platform and base plate as follows: bar19 is attached to platform 10 by rivet 20 which extends through aperture2| in wall I! and aperture 2i insaid bar and, by machine screw 22 whichextends through aperture 23 in wall ll'and aperture 23 in said bar,which screwis retained in place by wing nut 24, and

said bar is attached tobas'e plate 13 by rivet 25 which extends throughaperture 26 in wall is and aperture .255 in said bar and by machinescrew 2,! which extends through aperture 28 in wall 14 and aperture 28'in said bar and which plane and a punching bag;

screw is retained in place by wing nut 29; bar I8 is attached toplatform III by rivet 30 which extends through aperture 3I in wall IIand aperture 3| in said bar and by machine screw 32 which extendsthrough aperture 33 in wall Ii and aperture 33 in said bar and whichscrew 7 is retained in place by wing nut 34, and said bar is attached tobase plate I3 by rivet 35 which extends through aperture 315 in wall I4and aperture 36' in bar I8 and by machine screw 31 which extends throughaperture 38 in wall I 4 and aperture 38 in bar I8 and which screw isretained in place by wing nut 39.

Supporting bars !8 and I9 terminate respectively in outwardly anddownwardly turned apertured cars 40 and M. A substantially U-shapedbracket 42 terminating in outwardly-extending apertured cars 43 and 44is secured by rivets 45 and 46 to the portion of wall II of platform IIIfacing base plate I3. The elements of the above described device arepreferably made of sheet steel or aluminum which in the case of platformIt and base plate I3'may be drawn to form walls I! and I4 respectively.

In use, as a floor mount, the device is set upon the floor in theposition shown in Fig. 1, platform II) being substantially rigidlysecured to base plate I3 by bars I8 and I9. A metal sleeve 41 threadedatits lower end, to correspond with the internal threading of tubularportion I! of flanged fitting I6, is screwed home in said portion. Aninflated punching bag 48 is laced to a frusto-conically shaped block ofwood 49 which in turn is secured.

to a resilient rod 58 and the assembly consisting of said bag, block androd is vertically and slideably mounted in sleeve 4! and held at a fixedheight by set screw I. After adjusting the height of bag 48 by means ofset screw 5 I, the user stands upon platform I0 and strikes the bag. Theweight of the user. on platform I0 retains the mount and associatedelements in place on the floor, the bag, due to the resiliency of rod-50, being permitted to oscillate when struck.

When used as a wall mount, the device is placed in the position shown inFigs. 4 and 5. To accomplish this, after removing wing nuts 24 and 34,machine screws 32 and 22, securing bars I8 and I9 respectively toplatform 10, are disengaged, permitting platform I0 to be revolvable onrivets 3i] and 20. Platform I8 is then rotated 180 from the positionshown in Fig. 1 so that wall II extends upwardly. The device is then'brought against a wall such as wall 52 (see Fig. 4) and at a suitableheight, is secured thereto by fastening means. passed through theapertures in ears 43 and'44 of bracket 42. Base plate I3 is broughtupward until ears 49 and M of bars I8 and I9 come into contact with wall52 and then secured thereto by means of fastening means passing throughthe apertures in said cars. In this position, platform Ill extendslongitudinally in a horizontal plane. Punching bag 48 may then bemounted so as to depend from platform ID by the use of a mounting chain53 consisting of a threaded eye bolt. and matching nut 55, in which boltis mounted a double-linked element 56, the upper link 51 thereof passingthrough the eye bolt. The lower link 58 is slightly open so that loop 59of punching bag 48 may be secured to chain 53 by passing the said loopthrough the open portion of and into link '58. The mounting chain andpunching bag may then be secured to platform ID by passing the threadedshank of eye bolt 54 upward through a washer B8 and through aperture I2in 4 platform It, after which bolt 55 is screwed home on said threadedshank.

A user may then stand to one side of platform if] and strike punchingbag 48 which will hit against the underside of platform I6. By rhythmicpunching, the bag may be kept in constant motion in conventionalfashion.

Thus I have provided a novel and unique mount for a punching bag whichmay be used either as a floor model or as a wall model with no changesin structure or removal of parts required, except for the mere removalof a set of machine screws and wing nuts. It is to be emphasized that toconvert the mount from one form to the other does not require either theuse of tools or any alterations in or additions of parts, with the minorexception of the fastening means.

I have shown a preferred embodiment of my invention, but it is obviousthat numerous changes,

omissions and alterations may be made without departing from its spirit.Thus, the device could be made without ears 4!] and 4| at the end ofbars I8 and I9 respectively, in which event base plate I3 could besecured to wall 52 b means of fastening devices extending throughapertures such as apertures BI. In such event it would be preferable tofirst remove machine screws 21 and 3'! and wing nuts 29 and 39 and pivotbase plate I3 upwardly on rivets 25 and 35 so that the edges of wall I4would be flush against wall 52. Again, there would be no substantialdeparture from the embodiment illustrated to make base plate I3 andsupporting bars 58 and I9 unitary so that in effect, the mount wouldconsist of two articulate sections which may be either rigidly fastenedtogether, or by the removal of a set of machine screws and wing nuts, bepivotally connected.

Although I have described my invention with a certain degree ofparticularity, it is understood that the present disclosure has beenmade only by way of example and that numerous additional changes in thedetails of construction, combination and arrangement of parts may beresorted to without transcending the scope of the invention ashereinafter claimed.
